Do you consider yourself a multi-tasker? There’s ongoing debate whether multi-tasking is truly possible. On one side, some people feel more productive when juggling several tasks at once. On the other side, some studies show that the brain isn’t wired to switch focus back and forth effectively.
While multi-tasking is up for interpretation, there’s no question that being multi-talented is a great skill to have. That reminds us of the unassuming but overachieving graphic overlay.
Graphic overlays can go by several other names, including faceplate, nameplate, membrane switch overlay, and panel. Regardless of what you call it, the graphic overlay is typically used as the top layer of a membrane switch. Graphics are printed on a thin, durable substrate to create buttons, branding, instructional text, and other interface features for the user.
What you may be surprised to learn is that there are several uses of a graphic overlay.
First and foremost, a well-designed membrane switch can enhance the user experience and improve input accuracy for a wide range of electronic devices. When placed on top of a membrane switch, the graphic overlay provides a visual and even tactile interface. Raised, clickable buttons can be created by embossing the graphic overlay and placing metal domes between the overlay and conductive track.
Membrane switches are commonly incorporated in devices used in harsh environments or demanding conditions. The graphic overlay has potential to allow the membrane switch to be fully sealed, reducing the risk of moisture or debris damaging the buttons or internal components. In addition to a continuous surface, a graphic overly can feature films and coatings to make it resistant to:
Membrane switches are often more durable and rugged than other user interface options such as mechanical keyboards and touchscreens. This is partly due to the graphic overlay, which acts as a buffer layer between internal components and impact that could break or wear out the switches. Thanks to the durable material of the graphic overlays – often polycarbonate and polyester – the service life of a membrane switch can be millions of actuations.
Graphic overlays can be designed and produced with unique features that further enhance the user experience, including backlighting and dead fronting.
Last but not least, a graphic overlay can also include customized branding elements. Using the latest printing technology, you can design your overlay to feature logos, custom graphics, high-resolution imagery, accurate color selection, and other decorative details to help your product stand out.
